The Sensitivity Process is used to calculate the sensitivity of model results to variations in parameter values. It does this by computing the partial derivative of the objective function with respect to each parameter of interest.  This is in contrast to the method used by UCODE in which parameters are varied experimentally and the resulting effect on the objective function is observed directly.

The Sensitivity Process is not included in MODFLOW-2005 or MODFLOW-LGR.  External programs such as UCODE must be used instead.
